If the IV exhibits continous data you should draw a line graph, if it exhibits categoric data you should draw a bar chart

Questions

Results are repeated to ensure they are reliable and identify or minimise the effect of anomalies

Precise results are measured in a very small scale

An accurate result is the closest to the true value

A valid result is the one in which the confounding variables have been controled so that the only variable affecting the DV is the IV

Evaluation

First ask yourself if the data supports the conclusion, if it does use the axis or table labels to refer to the variables

Next ask yourself if the data contradicts the conclusion, to check for this check if the data talks about any control group; about sample size (larger sample gives you a more reliable mean since it reduces the effect of anomalies) and also check for the number of investigations done (increasing the number of investigations done reduces the effect of chance)
